The Sea Devils: | ||
 | ep 1,5 – | When the Doctor looks through a pair of binoculars at the castle in episode 1, the close-up of the castle is surrounded by a circular mask to indicate we are seeing it through the binoculars. But in episode 5 when the Admiral commanding the naval task force looks through his binoculars at the Sea Devil bodies floating in the water, we see them surrounded by a sideways-figure-of-8 mask instead. |
| ep 1 – | When Jo and the Doctor are climbing the ladder to get into the sea-fort, it's painfully obvious that it's not Katy Manning, but a cross-dressing stuntman wearing a Jo Grant wig. |
| ep 2 – | When the Doctor and Jo are carrying the fat guy out, for a split-second before the Sea Devil appears you can see shadows and light moving around in the background as if there's someone there.
[Which there undoubtedly is!] |
 | ep 2 – | While in the sea-fort, the Doctor rigs up the radio to transmit messages, but somehow still gets it to receive messages too. Handy, that. |
| ep 2 – | The radio that the Doctor built has a fatal flaw — if you look closely at the device (this is easiest to see right before it explodes), you can see that there's a 9-volt battery clip sticking out of it. But there isn't a battery in the socket, so the whole device shouldn't be able to work at all because there isn't a complete circuit.
[Somehow I doubt that the Doctor would let a small detail like that stop him.] |
| ep 2 – | The helicopter sent to rescue the Doctor and Jo acquires a new paint job in mid-flight. |
| ep 2,3 – | The clock on the wall in the Master's quarters causes a couple of continuity problems. When the Master pulls a gun on the Doctor and the Doctor quickly pulls the door shut, the clock shows ten minutes to three. In the next episode, after the swordfight is over and the Doctor is being led out by the guards, the clock now shows approximately eight minutes after twelve! |
| ep 3 – | A more subtle clock problem: when the Doctor is brought into the Master's quarters and handcuffed to the chair, the clock shows five minutes to one. Less than two minutes later (still in the same scene, with no cutaways), as the Master tells the Doctor he intends to contact "our reptile friends", the clock can be seen showing exactly one o'clock. |
| ep 3 – | Jo leaves her handbag behind in the prison while rescuing the Doctor, but suddenly reacquires it later without any explanation. |
| ep 3 – | When the Master arrives at the lifebelt post, the rope is surprisingly slack, considering that the Doctor is using it to climb down the cliff. |
| ep 4 – | At the naval base, the search for the missing sub is called off because of night approaching. Then the sub is picked up on radar approaching the castle. We see that it's getting dark when the Sea Devils arrive at the castle and rescue the Master. Then, just a few scenes later, Captain Hart and the others are still watching the radar screen as the sub is disappearing again, and Hart says they can resume searching in that area as "it'll be light soon". And indeed, a few minutes later they arrive at the castle, and it's daylight. Where did the night vanish to?
[Or did the Doctor and co. spend all night standing there watching the radar screen?] |
| ep 4,5 – | When the diving bell is raised, you can see drops of water on the camera lens which change position radically between shots, betraying the fact that the finished scene was edited down from a much longer sequence. |
| ep 6 – | When the Doctor turns on the sonar device (causing the Sea Devils to writhe around in pain), the Master just stands there for over a minute watching a Sea Devil throwing a fit in front of him — long enough for Jo and Captain Hart to escape to the hovercraft — before saying "What are you doing?!" and turning it off! |
